SN74FB1653的产品详情：

The SN74FB1653 contains an 8-bit and a 9-bit transceiver with a buffered clock. The clock and transceivers are designed to translate signals between LVTTL and BTL environments. The device is designed specifically to be compatible with IEEE Std 1194.1-1991 (BTL).

The A port operates at LVTTL signal levels. The A outputs reflect the inverse of the data at the B\ port when the A-port output enable (OEA) is high. When OEA is low or when V_CC(5 V) typically is less than 2.5 V, the A outputs are in the high-impedance state.

The B\ port operates at BTL signal levels. The open-collector B\ ports are specified to sink 100 mA. Two output enables (OEB and OEB)\ are provided for the B\ outputs. When OEB is low, OEB\ is high, or V_CC(5 V) typically is less than 2.5 V, the B port is turned off.

The clock-select (2SEL1 and 2SEL2) inputs are used to configure the TTL-to-BTL clock paths and delays (refer to the MUX-MODE DELAY table).

BIAS V_CC establishes a voltage between 1.62 V and 2.1 V on the BTL outputs when V_CC(5 V) is not connected.

BG V_CC and BG GND are the supply inputs for the bias generator.

V_REF is an internally generated voltage source. It is recommended that V_REF be decoupled with a 0.1-µF capacitor.

Enhanced heat-dissipation techniques should be used when operating this device from AI to A0 at frequencies greater than 50 MHz, or from AI to B\ or B\ to A0 at frequencies greater than 100 MHz.
